The recommended way to install Rasa Core is using pip:
pip install rasa_core
Unless you’ve already got numpy & scipy installed, we highly recommend that you install and use Anaconda.
If you want to use the bleeding edge version of Rasa use github + setup.py:
git clone https://github.com/RasaHQ/rasa_core.git cd rasa_core pip install -r requirements.txt python setup.py install
If you want to change the Rasa Core code and want to run the tests or build the documentation, you need to install the development dependencies:
pip install -r dev-requirements.txt
We use Rasa NLU for intent classification & entity extraction, but you are free to use other NLU services like wit.ai, api.ai, or LUIS.ai. If you want to use Rasa NLU make sure to follow the installation instructions of the NLU docs as well. In fact, you don’t need to use NLU at all, if your messaging app uses buttons rather than free text.
